Donald Trump hits on a sore point with Brussels 'coddling' remarksUK's Prevent strategy has been contentious but lack of community police work in Brussels may have left dangerous vacuum

Donald Trump's implied portrayal of Muslim communities as the "enemy within", with his declaration to Piers Morgan that they are not reporting terrorist suspects, follows his claim in December that parts of UK cities are so radicalised they are no-go areas for the police.

Scotland Yard responded then that "Trump couldn't be more wrong". The force has been equally robust in rejecting the Republican contender's questioning of the loyalty of Britain's Muslim communities.

As Scotland Yard's head of counter-terrorism, Mark Rowley, told MPs last July: "Over the last year we have had far more information from communities about people of concern, some of whom we have been able to intervene with in a preventative sense, which is really positive, and I see an appetite from the majority of communities to work with us and tackle this."
